Advantages and Disadvantages of electro galvanized steel:
Advantages of electro galvanized steel:
1. Thin coating: The zinc layer in electro galvanized steel is thinner than that in hot-dip galvanizing, typically ranging from 5 to 20 micrometers. As a result, the surface is smooth and does not alter the dimensions or shape of the steel.
2. Uniformity: The zinc coating is uniform and can be applied to the surfaces of objects with complex shapes, such as screws and nuts.
3. Low Cost: The production cost of electro galvanized steel is relatively low because it does not require heating and cooling, unlike hot-dip galvanizing.
4. Environmental friendliness: The electro galvanized steel process does not produce exhaust gases or wastewater, resulting in a minimal environmental impact.

Disadvantages of electro galvanized steel:
1. Poor corrosion resistance: The zinc coating in electro galvanized steel is thinner than that in hot-dip galvanizing, so its corrosion resistance is relatively poor; it is particularly prone to rusting in humid and corrosive environments.
2. Poor wear resistance: The zinc coating in electro galvanized steel is thinner than that in hot-dip galvanizing, resulting in relatively poor wear resistance; it is prone to scratches and abrasion.
3. Limited scope of application: Electro galvanized steel is typically used for steel products in indoor settings and mildly corrosive environments, such as furniture, appliances, and automotive parts.

What is P20 material?
P20 is a pre-hardened plastic mold steel, corresponding to the Chinese national standard 3Cr2Mo and the German standard 1.2311.

P20 contains alloying elements such as chromium and molybdenum, has a uniform microstructure, well-controlled impurities, stable machining performance, reasonable tool wear, and good surface finish. It is suitable for making structural parts such as cavities, cores, and mold frames. Upon arrival, it can be directly milled, ground, drilled, and EDM machined without additional quenching and tempering, shortening the mold making cycle and reducing precision issues caused by heat treatment deformation.

Its polishing performance meets the requirements of most plastic exterior parts, adapting to the surface standards of molds for household appliance housings, automotive interiors, and daily necessities. It can also undergo nitriding treatment to improve wear resistance.
